They live in the delightfully hand painted wooden box. I believe them to have belonged to my great uncle, and that they were given to my brother and me by my Grandma when we were young. I’m going to check this and report back.
For some reason, probably more than 15 years ago, one of these pens was nib up in a cardboard box full of presents at Christmas time. Reaching in to the box my thumb was impaled, and a small particle of ink from the nib lodged under the skin. To this day my first tattoo is still visible!
